Introduction

Special Features of the System Board

Hyper-Threading Technology Functionality Requirements
The system board supports Intel processors with Hyper-Threading
Technology. Enabling the functionality of Hyper-Threading Technology
for your computer system requires ALL of the following platforms.
Components:
® ®
• CPU - an Intel Pentium 4 Processor with HT Technology
®
• Chipset - an Intel chipset that supports HT Technology
• BIOS - a BIOS that supports HT Technology and has it enabled
• OS - an operating system that includes optimizations for HT
Technology
Refer to Appendix A for information about enabling the functionality
of the Hyper-Threading Technology. For more information on Hyper-
Threading Technology, go to: www.intel.com/info/hyperthreading.
Performance Acceleration Technology (PAT)
PAT mode is supported only when the system uses DDR400 with
800MHz FSB CPU. PAT performs data transactions directly from the
CPU to the system memor y, bypassing the normal path of
operation. This reduces the MCH timing therefore providing
improved system performance.
CPU Fan Protection
The CPU Fan Protection function has the capability of monitoring the
CPU fan when the system boots. Once it has detected that the CPU
fan did not rotate, 5 warning beeps will sound then the system will
automatically power-off. This preventive measure has been added to
protect the CPU from damage and insure a safe computing environ-
ment.
CPU Temperature Protection
The CPU Temperature Protection function has the capability of
monitoring the CPU's temperature during system boot-up. Once the
system has detected that the CPU's temperature exceeded the
temperature limit defined in the BIOS, 5 warning beeps will sound then
the system will automatically power-off.
